About Centrifugal Fans: A centrifugal wheel brings air in parallel to the axis of rotation and discharges air perpendicular to the axis of rotation. As a general rule, it is preferred for higher pressure exhaust and ducted systems

CP’s are ideal for low to medium volume and pressure applications. They are available in a number of wheel options for maximum performance flexibility.

Blade type

Backward Inclined Airfoil: Has the highest efficiency of all of the centrifugal impeller designs with blades of airfoil contour curved away from the direction of rotation. Air leaves the impeller at a velocity less than its tip speed. Relatively deep blades provide for efficient expansion with the blade passages. For the given duty, the airfoil impeller design will provide for the highest speed of the centrifugal fan designs.

Backward Inclined Flat Blades: Efficiency is slightly less than that of the airfoil design. Blades are single thickness metal inclined away from the direction of rotation. Air leaves the impeller at a velocity less than its tip speed. Relatively deep blades provide efficient expansion with the blade passages.

Forward Curved: Efficiency is less than airfoil and backward curved bladed impellers. Has blades with both the heel and tip curved forward. Air leaves the impeller at velocities greater than the impeller tip speed. For the given duty, the wheel is the smallest of all of the centrifugal types and operates most efficiently at lowest speed.
